单髁置换术与全膝关节置换术治疗膝关节单纯内侧间室骨性关节炎近期疗效的对比研究

Effectiveness Comparison of Unicondylar Knee Arthroplasty and Total Knee Arthroplasty in the Treatment of Knee Osteoarthritis

目的比较单髁置换术与全膝关节置换术治疗膝单纯内侧间室骨性关节炎的近期疗效。方法选取2013年1月至2016年1月,于我院就诊的膝单纯内侧间室骨性关节炎患者61例,分为单髁置换组(n=26)与全膝关节置换组(n=35),对比两组患者的治疗效果。结果两组患者术后HSS评分差异不显著(P>0.05),但单髁置换组患者术后膝关节屈曲度和疼痛缓解率显著高于全膝关节置换组(P<0.05);单髁置换组患者术中出血量、术后3 d血红蛋白下降量、住院时间均显著低于全膝关节置换组(P<0.05)。结论单髁置换术与全膝关节置换术治疗膝单纯内侧间室骨性关节炎近期疗效相似,但单髁置换术治疗的术中出血量更少,住院时间更短,有利于患者术后恢复。

Objective To compare the short-term clinical effects of unicondylar knee arthroplasty（UKA） and total knee arthroplasty（TKA） in the treatment of knee osteoarthritis. Methods From January 2013 to January 2016, 61 patients with medial unicondylar knee osteoarthritis were divided into unicondylar replacement group（ n=26） and total knee arthroplasty group（n=35）. The short-term clinical results of the two groups were compared. Results The difference of postoperative HSS score in both groups was not significant（P〈0.05）. However, the range of motion in the UKA group was significantly bigger than TKA group（P〈0.05）; The rate of pain relieve, blood loss, hemoglobin decrease on 3 day after operation and hospitalization stay in the UKA group were all significantly better than TKA group（P〈0.05）. Conclusion The short-term results of unicondylar knee arthroplasty and total knee arthroplasty for the treatment of knee osteoarthritis are similar.However, the unicondylar knee arthroplasty is more beneficial to postoperative recovery with less intraoperative bleeding and shorter hospital stay.
